The S50B32 is a thing of beauty. This was the E36 M3 motor we did not get in the States but should have if BMW respected us. Well, too late for that, but not too late for Active Autowerke to release a supercharger for the popular motor. Unlike the US S50's, the S50B32 has indpendent throttle bodies and you can see how the Active manifold feeds into them. The blower used is an HKS unit likely the GTS8550. Pricing has not been revealed yet but a teaser dyno shows gains of 124 whp, very nice.
